Abstract (en)
[origin: WO0137294A1] The invention concerns connection systems for a submarine acoustic antenna. It consists in connecting the antenna (201-206) to elements (102) of the sonar by an optical link. A removable transformer (210, 211) enables to separate galvanically the antenna and the transmission means. It powers a VCSEL electro-optical element (216) which energises an optical fibre (217) connected to the pressure hull penetrators (108). The invention enables to produce an antenna having a very large number of sensors.
